Most likely yes, plant those babies. I did a hermie project earlier this year, took 20 beans from a she/he mother to see what would happen. Of those 20, 16 were straight females with no tendency to become hermaphrodites. The other 4 were straight male.
I may actually screw up a light cycle or 2 on my next grow for more feminized beans. However, certain strains will pass along self-pollination characteristics...it's almost unavoidable with certain sativa land race varieties.
